PT6312R Equivalent & Substitute Parts

Part Overview

The PT6312R is a non-isolated Point-of-Load (PoL) module DC-DC converter manufactured by Texas Instruments, designed for commercial Information Technology Equipment (ITE) applications. This component delivers a fixed 15V output at up to 2A from a 19V to 38V input supply. The PT6312R is classified as obsolete, necessitating identification of functionally equivalent active alternatives to support ongoing system requirements and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PT6312R is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Single output configuration with fixed 15V output voltage
• Maximum output current of 2A
• Input voltage range compatibility (minimum 19V requirement)
• Operating temperature range of -40°C to 85°C
• Through-hole mounting type with 12-SIP module package

Regulatory & Compliance Criteria:

• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status
• EAR99 ECCN classification

The R-7215P from Recom Power satisfies all critical substitution parameters. While the R-7215P has a reduced maximum input voltage (28V versus 38V), it maintains full compatibility with the standard 19V minimum input requirement and delivers identical output specifications (15V at 2A). The substitute part is currently in active production status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The R-7215P is the qualified substitute for the obsolete PT6312R based on the following engineering factors:

Compliance & Certification Alignment: Both components maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory continuity in applications requiring these certifications.

Functional Equivalence: The R-7215P delivers identical electrical performance in the standard operating envelope: 15V output at 2A with -40°C to 85°C temperature range. The 12-SIP module package and through-hole mounting type provide direct mechanical compatibility.

Product Status & Availability: The R-7215P is in active production status with documented inventory availability, eliminating obsolescence risk associated with the PT6312R. This transition supports long-term supply chain stability for new designs and legacy system support.

Input Voltage Consideration: The R-7215P maximum input voltage of 28V is suitable for applications operating within standard 19V to 28V input ranges. Systems requiring the full 38V input capability of the PT6312R require alternative evaluation.

Performance Enhancement: The R-7215P achieves 97% efficiency compared to the PT6312R's 87%, resulting in reduced thermal dissipation and improved power conversion performance.

Frequently Asked Questions (FAQ)

Q: Can the R-7215P directly replace the PT6312R in existing designs?

A: The R-7215P is mechanically and electrically compatible for applications operating within its 19V to 28V input voltage range. If your system requires input voltages above 28V, alternative evaluation is necessary. Both components share identical 12-SIP through-hole package specifications and deliver 15V at 2A output.

Q: What is the primary difference between these two converters?

A: The primary difference is input voltage range. The PT6312R accepts 19V to 38V input, while the R-7215P accepts 19V to 28V input. The R-7215P offers superior efficiency (97% versus 87%) and active product status. Output specifications and thermal operating range are identical.

Q: Are there compliance or certification differences?

A: No. Both components are ROHS3 compliant, MSL Level 1 (Unlimited), and REACH Unaffected. Regulatory and environmental compliance requirements are fully satisfied by the R-7215P.

Q: What packaging is used for the R-7215P?

A: The R-7215P is supplied in Tube packaging and maintains the 12-SIP module form factor with dimensions of 1.27" L x 0.36" W x 0.59" H (32.2mm x 9.1mm x 15.0mm), ensuring compatibility with existing through-hole PCB layouts.

Q: Does the R-7215P include additional control features?

A: Yes. The R-7215P includes Remote On/Off capability, Short Circuit Protection (SCP), and Enable control with Active High logic. The PT6312R specifications do not document these features.

Q: What is the power rating difference?

A: The R-7215P is rated at 30W (15V × 2A), which matches the PT6312R output capability. The R-7215P's higher efficiency rating (97%) indicates superior thermal performance at this power level.
